Researchers have introduced a novel approach called "Meta Expert" for Mixture-of-Experts (MoE) models, aiming to improve efficiency by sharing experts across different layers. This method contrasts with traditional MoE models that use layer-specific "Local Experts." Empirical comparisons show that Meta Experts reduce parameter redundancy, leading to lower cross-entropy loss and higher accuracy on downstream tasks. The Meta Expert model can achieve performance comparable to Vanilla MoE while using 70-80% of the experts, demonstrating significant potential for scaling. AI
